There is a roller rolling disc alternating motion to the heat treated and precisely grinded guide shaft.

To withstand four directional loads acting on the LM sliding block, (such as radial, reverse radial and bending) the shaft and roller have 60 degrees in contact angle. It can increase normal strength keeping up the constant and low friction coefficient because it can apply balanced preloads in any conditions.

Both height and the coefficient of friction between the shaft and high strength roller bearing are low. So, it serves high stabilized rectilinear motion with high speed. The existing rail was not very good in appearance because of the holes on the top. But, the RT rail can be tide up to the bottom, so it has fine design and attains a smooth sliding effect.
